Unlike conventional earplugs, there's no need to roll and compress them. Easy and smooth insertion is achieved by simply twisting and gently pushing them in, ensuring excellent hygiene. Once properly inserted, they don't expand and effectively cut out noise. Noise reduction rating: 29dB. Easy to insert with new material, Quick-In. Just "putting in earplugs" can improve sleep, concentration, and efficiency in business/study! Use them on trains, buses, or during air travel for a good night's sleep while traveling. They're also great for sharing a room with someone who snores. ● Effectively cuts out annoying and harmful high-frequency noise. ● Noise levels of 85-95dB at busy intersections are reduced to below 60dB, similar to a quiet office.
